(CBSNewYork) – The NYPD is stepping up their war against illegal guns,
with a new tool that could detect weapons on someone as they walk down
the street.

But is it violating your right to privacy?

Police, along with the U.S. Department of Defense, are researching new
technology in a scanner placed on police vehicles that can detect concealed
weapons.

“You could use it at a specific event. You could use it at a shooting-prone
location,” NYPD Commissioner Ray Kelly told CBS 2?s Hazel Sanchez on Tuesday.

It’s called Terahertz Imaging Detection. It measures the energy radiating
from a body up to 16 feet away, and can detect anything blocking it, like
a gun.

“I think it’s good. People will be safer and it will be a safer environment,”
Jessica Ramos said.

“I think it’s all about invading people’s lives more and more and more,”
Antonio Gabriel added.

Police Commissioner Kelly said the scanner would only be used in reasonably
suspicious circumstances and could cut down on the number of stop-and-frisks
on the street.

But the New York Civil Liberties Union is raising a red flag.

“It’s worrisome. It implicates privacy, the right to walk down the street
without being subjected to a virtual pat-down by the Police Department
when you’re doing nothing wrong,” the NYCLU’s Donna Lieberman said.

“We have involved our attorneys as we go forward with this issue. We
think it’s a very positive development,” Kelly said.

People on the street have differing opinions on the price they’d be
willing to pay for safety.

“If they search you, you’re not giving consent, so they can do what
they want, meaning they can use that as an excuse to search you for other
means. I don’t think that’s constitutional at all,” Devan Thomas said.

“I think it’s good. I think if someone has something to hide and they’re
going to worry about it, who cares?” Robert McDougall added.
